Problem 1 A model rocket has engine with an average thrust of 6.92 N. The rocket mass is 72.5g,which includes fuel mass 22.3 g. The duration of fuel burning is 2.52 s a) What is the average exhaust speed v, of the engine? (12 points) b) What is the final speed i of this rocket if it were to be fired from International Space Station with initial speed v-7660 m/s? Assume the fuel burns at a constant rate (13 points)...

A small sounding rocket has an initial mass of M=3200kg (80% of which is fuel) and burns fuel at a rate of 20 kg/s. The exhaust velocity of the gas ejected from the rocket is Uex=2000m/s. a. Find the thrust of the rocket motor. b. Find the time until burnout. c. Find the speed of the rocket at burnout assuming that the rocket moves straight up and stays close enough to Earth's surface that the gravitational acceleration is always g=9.81m/s^2

A turbojet engine in a wind tunnel receives air at a velocity of U;= 100 m/s and a density of p.= 1 kg/m' The velocity is uniform and the cross-sectional area of the approaching stream which enters the engine is A = 0.1 m² The velocity of the exhaust jet from the engine, however, is not uniform but has a velocity which varies over the cross-section according to u. = 20 (1-PIR) where the constant U=600...

Problem 1: The angular velocity of flywheel decreases uniformly from 12000rev/min to 3000 rev/min in 8 sec. Find the angular acceleration and the number of revolutions made by the wheel in the 8 sec interval. How many more seconds are required for the wheel to come to rest? Problem 2: A uniform meter scale...
